Not all SS vertical hangers have bottom stiching. see pages 587 - 603 of TW's book.

If you look on page 598 of that SS booh, you will see the center vertical has a similar construction to yours. It is mine and if you need pics, just ask.

The thing that would make me reluctant to purchase the one you show is the clip. That type of metal with that incuse stamp is usually the sign of a fake. Sorry.
